Harsh...
Some of those reviews were a bit black and white, but all together, I think you did an excellent job in parodying Wacky Races, some people just cant get the dicks out of their eyeballs to see the point of this spoof is just intended for pointless humor. I even love how the voice quality and dialog was dead-on to that of the time of the Wacky Races. Hell you did Wacky Races a favor by juxtaposing them to something a little more mainstream, enlightening the younger audience.
Kudos to you sir, And may the force be with you!
